I was making a logo for an indoor soccer team I play on just for fun and decided to adjust it to be a Wizards logo. You can see the result above and variations below/inside. The first uses only the two blues, yellow and blue which appear to be the 2008 color scheme and no black (This is assumed by looking at season ticket ads).
This has a moon, I have not been able to come up with many Wizard themes that are not a Wizard and I’ve not been able to make or find a wizard that is worthy of being on a logo. The more I’ve messed around with logos for the Wizards name the more I think they are going to re-brand the team all together.
If you want to take these and make variations which are better feel free to.
Also if you are interested in making your own to share with the world, but don’t own and can’t afford Photoshop there are two free programs that can do much of the same stuff. Each with link below.
Paint.net -This one feels a lot like Photoshop, I have not found a way to edit text after making it the first time though. Any way check out the wikipedia page or the official page if you are interested.
